EXP Rush!

This should be everyone's primary focus till Reaper of Souls launches. The 50% experience is not worth passing up and, its confirmed that items can only roll stats at the level of the item rather than the level of the character. This makes all but extreme cases of jewelry useless as armor and non percentage based stat rolls are considerably higher at level 70.

That was my same focus as well. Even reset quests numerous times. Then I learned that basically everything I get now is completely useless with only a few exceptions (like my Ess of Johan with 80% slow [max] and Tal's ammy with 20% Fire and 96CD) That's why I've been running Cathedral Level 4. A Wizard with Frozen Orb can clear the entire level's trash in a few minutes for about 1B exp/hr while solo. A good T6 group can double that.

I have actually yet to find a legendary in there, except for the goblin in the ruins basement. At one point I would run CotA, then take the ruins WP, grab the white in Griswold's corner, then check the cellar that can spawn the go Lin and the one that can spawn the cursed chest.
